So, they've been together about 5 hours or so, and so far no major squabbles or injuries have occurred. Scarlette and Twilight who are sisters seem to pretty much ignore one another, as do Lily and Luna who are also sisters. Even though there's a huge size difference between the two pair, the little girls seem to be holding their own, and I'm glad I made the decision to get little Luna instead of another of the bigger girls at the other store. Scarlette seems to be the dominant girl,and she has chosen her territory behind a big plant under the filter where she's near impossible to photograph, but here are the clear pics I managed to get of the girls.

Scarlette:

Twilight: (not exactly my favorite fish, she's not even the one I had picked out, apparently the girl netted the wrong fish and I didn't notice until I got home, but regardless she's pretty in her own way)

Thanks! Luna and Lily are my favs too, I'm really protective of them, every time i see the bigger girls nearing them my heart skips a beat, but so far the only one with a nipped fin is Twilight, and she had that when I got her. Twilight has turned out to be quite the chaser now that she's come out of her shell, so far it just seems like a game to her to chase the little ones around, she always turns away if she catches up.. but I'm watching her closely.. the little girls are SO tiny compared to the others.
